Answer:

because the Earth rotates, circulating air is deflected. Instead of circulating in a straight pattern, the air deflects toward the right in the Northern Hemisphere and toward the left in the Southern Hemisphere, resulting in curved paths. This deflection is called the Coriolis effect.

Explanation:

The following are the environmental problems caused by the invasive algae which is known as Lyngbya.

A. It blocks the sunlight from reaching the water, thereby depriving the plants in the water from accessing it. So they won't be able to manufacture their foods and eventually die off.

B. The algae produce offensive odour like rotten egg , which drive people and other organisms away.

C. The algae prevent oxygen from entering the water, and prevent the resident organisms from making use of it, which leads to their death.

D. The algae also give off heat into the chilly spring waters.

In conclusion, the goals of the Crystal River project is to save the living organisms in the river from extinction and to make it a livable environment for them.

Answer:

the answer is (b) Kg ms-1 .

Answer:

y = 0.99 m

Explanation:

This is a projectile launching exercise, let's start by finding the components of the initial velocity, using trigonometry

         cos θ = v₀ₓ / v₀

         sin θ = v_{oy} / v₀

         v₀ₓ = vo cos θ

         v_{oy} = I go sin θ

         v₀ₓ = 15 cos 30 = 12.99 m / s

         v_{oy} = 15 sin 30 = 7.5 m / s

Let's find the time it takes to travel x = 18 m

         x = v₀ₓ t

         t = x / v₀ₓ

         t = 18 / 12.99

         t = 1,385 s

at this point it is at a height of

         y = v_{oy} - ½ g t²

         y = 7.5 1.385 - ½ 9.8 1.385²

         y = 0.99 m

therefore the camera must place the foot 99 cm from the ground

Explanation:

Velocity (v) is a vector quantity that measures displacement (or change in position, Δs) over the change in time (Δt), represented by the equation v = Δs/Δt. Speed (or rate, r) is a scalar quantity that measures the distance traveled (d) over the change in time (Δt), represented by the equation r = d/Δt.

In fact, it is the natural tendency of objects to resist changes in their state of motion. This tendency to resist changes in their state of motion is described as inertia. Inertia = the resistance an object has to a change in its state of motion.

Answer:

Freefall is a special case of motion with constant acceleration because acceleration due to gravity is always constant and downward. This is true even when an object is thrown upward or has zero velocity.

When a ball is thrown up in the air, its velocity is initially upward. Since gravity pulls the object toward the earth with a constant acceleration g, the magnitude of velocity decreases as the ball approaches maximum height. At the highest point in its route, the ball has zero velocity, and the magnitude of velocity increases again as the ball falls back toward the earth.

Answer:

Acceleration from gravity is always constant and downward, but the direction and magnitude of velocity change. At the highest point in its trajectory, the ball has zero velocity, and the magnitude of velocity increases again as the ball falls back toward the earth

Complete question:

A 200 g load attached to a horizontal spring moves in simple harmonic motion with a period of 0.410 s. The total mechanical energy of the spring–load system is 2.00 J. Find

(a) the force constant of the spring and (b) the amplitude of the motion.

Answer:

(a) the force constant of the spring = 47 N/m

(b) the amplitude of the motion = 0.292 m

Explanation:

Given;

mass of the spring, m = 200g = 0.2 kg

period of oscillation, T = 0.410 s

total mechanical energy of the spring, E = 2 J

The angular speed is calculated as follows;

[tex]\omega = \frac{2\pi}{T} \\\\\omega = \frac{2\pi}{0.41} \\\\\omega = 15.33 \ rad/s[/tex]

(a) the force constant of the spring

[tex]\omega = \sqrt{\frac{k}{m} } \\\\\omega^2 = \frac{k}{m} \\\\k = m \omega^2\\\\k = (0.2)(15.33)^2\\\\k = 47 \ N/m[/tex]

(b) the amplitude of the motion

E = ¹/₂kA²

2E = kA²

A² = 2E/k

[tex]A = \sqrt{\frac{2E}{k} } \\\\A = \sqrt{\frac{2\times 2}{47} }\\\\A = 0.292 \ m[/tex]

Answer:

The appropriate solution is "61.37 s".

Explanation:

The given values are:

Boat moves,

= 10 m/s

Water flowing,

= 1.50 m/s

Displacement,

d = 300 m

Now,

The boat is travelling,

= [tex]10+1.50[/tex]

= [tex]11.5 \ m/s[/tex]

Travelling such distance for 300 m will be:

⇒ [tex]v = \frac{d}{t} \ sot \ t[/tex]

      [tex]=\frac{d}{v}[/tex]

On putting the values, we get

      [tex]=\frac{300}{11.5}[/tex]

      [tex]=26.08 \ s[/tex]

Throughout the opposite direction, when the boat seems to be travelling then,

= [tex]10-1.50[/tex]

= [tex]8.5 \ m/s[/tex]

Travelling such distance for 300 m will be:

⇒ [tex]v=\frac{v}{t} \ sot \ t[/tex]

      [tex]=\frac{d}{v}[/tex]

On putting the values, we get

      [tex]=\frac{300}{8.5}[/tex]

      [tex]=35.29 \ s[/tex]

hence,

The time taken by the boat will be:

= [tex]26.08+35.29[/tex]

= [tex]61.37 \ s[/tex]

Answer:

(a) 0.0165 m

(b) 16.5 m

Explanation:

Applying,

v = λf.................. Equation 1

Where v = velocity, f = frequency, λ = wave length.

make λ the subject of the equation

λ = v/f............. Equation 2

(a) Shortest wavelength (λ')

Given: f' = 20000 Hz, v = 330 m/s

Substitute these values into equation 2

λ' = 330/20000

λ' = 0.0165 m

(b) Longest wavelength (λ)

Given: v = 330 m/s, f = 20 Hz

Substitute these value into equation 2

λ = 330/20

λ = 16.5 m

The speed of an object is the distance traveled in unit time, while acceleration of an object is the rate of change of velocity in respect to time

Answer:

C.

Explanation:

Swapping electrical charges will always have to do with electrons, so A & B can be eliminated easily.

Electrons will be the ones transferring over to the new object. Electrons are naturally negatively charged, so anything that gains electrons will become negatively charged themselves. Whereas if they lose electrons, they will become positively charged.

It's worth noting that protons and electrons have the same exact numerical charge, but they are both opposites. Electrons are negative, and protons are positive. Neutrons on the other hand have no charge (hence the "neutral" root in its name).

Answer:

The thermal energy gained by the water during the entire process is 90,372 J

Explanation:

Given;

mass of the ice cube, m = 30 g

latent heat of fusion of ice, L = 334 J/g

specific heat capacity of water, C = 4.184 J/g⁰C

latent heat of vaporization of water, h = 2260 J/g

The thermal energy gained by the water during the entire process is calculated as;

[tex]Q_t = Q_{fusion-ice} \ + \ Q_{boil-water} \ + \ Q_{steam-vapor}[/tex]

The heat of fusion of the ice at 0⁰C is calculated as;

[tex]Q_{fusion} = mL = 30\ g \times 334 J/g = 10020 \ J[/tex]

The heat of capacity of the water from  0⁰C to 100 ⁰C

[tex]Q_{boil-water} = mc\Delta \theta = mc(100-0) = 30\ g \times 4.184\ J/g^0C \times 100\ ^0C = 12,552 \ J[/tex]

The heat of vaporization of the steam at 100⁰C is calculated as;

[tex]Q_{steam} = mh= 30 g \times 2260 \ J/g= 67,800 \ J[/tex]

The thermal energy gained by the water during the entire procees;

Qt = 10,020 J  +  12,552 J   +  67,800 J

     = 90,372 J

Therefore, the thermal energy gained by the water during the entire process is 90,372 J

Answer:

The answer is option C.Half as much

The correct answer is four times as much.

Let the friend's mass be m, then according to the question the bodybuilder's mass will be 2m.

Now they both cover the same distance but the bodybuilder takes 4s and his friend takes 2s. Hence, if the time taken by the friend is t then the bodybuilder takes 2t time.  

That means if the velocity of the bodybuilder is v then the velocity of his friend will be 2v.

Now, Power is defined as the rate of work done.

P = W/t

and work done is the change in kinetic energy.

Now the power generated by the bodybuilder is:

[tex]P_{b}=\frac{\frac{1}{2}2mv^{2} }{2t} \\\\P_b=\frac{mv^2}{2t}[/tex] ............(1)

power generated by the friend is :

[tex]P_{f}=\frac{\frac{1}{2}m(2v)^{2} }{t} \\\\P_b=\frac{4mv^2}{2t}[/tex].............(2)

Comparing (1) and (2) we get:

The friend generates four times as much power as the bodybuilder.
